The aim of this study is to check the efficiency of boron in refining lamellar microstructures of
TiAl alloys densified by Spark Plasma Sintering. Boron-containing TiAl47Cr2Nb2B0. 6 and …

This work presents a study of the Spark Plasma Sintering of a boron and tungsten containing
alloy (Ti 49, 92 Al 48 W 2 B 0, 08, called IRIS) as a function of the sintering temperature …

The microstructure evolution and room temperature mechanical property of beta containing
Ti–44Al–3Nb–1Mo–1V–0.2 Y alloy consolidated by spark plasma sintering was studied. Pre …

In the present study, the spark plasma sintering technique is used to densify pre-alloyed TiAl
powders. Ti49Al47Cr2Nb2 and Ti51Al44Cr2Nb2B1 powders are sintered at temperatures …

This work deals with the densification of TNM alloys by spark plasma sintering. Pre-alloyed
powders with composition Ti–43.9 Al–4Nb–0.95 Mo–0.1 B (at.%) were sintered between …

Two-phase near TiAl alloys have been developed in the last two decades for high
temperature structural applications [1]. The alloys with the fully lamellar structure have been …

Spark Plasma Sintering (SPS) is used to process TNB alloys. Pre-alloyed powders (Ti–46Al–
9Nb) were sintered between 975° C and 1300° C under 100MPa. The microstructures of the …

Abstract The synthesis of Ti–44Al–5Nb–2Cr–1.5 Zr–0.4 B–0.07 La and Ti–44Al–5Nb–1Cr–
1.5 Zr–1B–0.17 La (at%) intermetallics was performed from pure metals by the electron …

Abstract Effects of trace TiB 2 addition on the solidification microstructure of Ti–48Al–2Cr–
2Nb+(0.18, 0.54, 0.9) wt.% TiB 2 alloys were investigated by arc melting and …

Various cast or wrought fully lamellar TiAl-based alloys with and without boron addition have
been assessed. It has been found that titanium boride precipitates are the predominant …
